Features of the MSM Flashcards
What are the AO3 points to evaluate features of the MSM?
For capacity + duration of STM and coding of STM and LTM :
- high control over extraneous variables
- high reliability
- lacks mundane realism
Duration of LTM:
- high in mundane realism
- low control over extraneous variables
What are the AO3 points to evaluate capacity + duration of STM and coding of STM and LTM?
- high control over extraneous variables
- high reliability
- lacks mundane realism
P
(high control over extraneous variables)
research into (duration of STM) lacks mundane realism
E
as task of (recalling consonant trigrams) is artificial
E
- therefore difficult to gen findings (that info lasts bw 18 - 30 seconds) to rl examples of (duration of STM)
- as research does not reflect real life activities where what we are trying to remember is meaningful
L
- therefore lowering ext val of research into duration of STM
- however some would argue we do try to remember meaningless things such as a group of digits for a phone number, therefore although task is artificial, does have relevance to rl
P
(high control over extraneous variables)
research into (coding of LTM) has high control over extraneous variables
E
as it was carried out in a controlled setting of a lab, e.g. (lists of words would be matched on their difficulty with each word shown to ppts for same amount of time)
E
this means we are more likely to est cause and effect bw IV (list of words) and DV (accurate recall)
L
therefore inc int val of research into (coding of LTM)
P
(high reliability)
research into (capacity of STM) is praised for having high reliability
E
this is coz research was carried out in controlled env of a lab
E
- therefore research can be repeated in same conditions of (same standardised intructions, same digits given to ppts and shown for same amount of time)
- to check for consistent results
L
Therefore inc int val
What are the two AO3 points to evaluate Bahricks duration of the LTM?
- high in mundane realism
- low control over extraneous variables
P
(high in mundane realism)
Bahricks research into duration of the LTM is high in mundane realism
E
this is coz research assessed rl memories of indv classmates
E
this is a rl example in everyday life e.g. searching for old friend on social media
L
therefore it may be easier to gen findings of duration of LTM to other rl applications, inc ext val
P
(low control over extraneous variables)
However, some may argue research into duration of LTM has low control over extraneous variables as research took place in a controlled env
E
e.g. how much contact ppts had with classmates after leaving school was not controlled
E
therefore cause and effect cannot be est bw IV of length of time passed and DV of accurate recall of classmates
L
therefore firm conclusions cannot be made on duration of LTM, reducing int val of research findings
